That's not very useful tbh. If you want to question their technical knowledge, ask for their road-map, what technologies they're looking into to adopt, what their tech-stack is, if and how they plan to migrate their legacy stuff, and their idea of an ideal dream setup. I also ask 'company culture' related questions, my go-to question is ask what the team I would end up in did as a teambuilding event last year, and follow up with who decided the type of event. It tells you a lot on the freedom you'll get, the company's attitude towards people working there, and how healthy the company is.
